Hope this isn't to crazy of a question but does anyone know--{CANE POLE}--if interference will show up on sonar with the trolling motor out of the water? The noise is definitely trolling motor related. Every time you hit the go switch on the motor it puts a vertical line on the sonar screen. I haven't tried it yet but it would be great if it will do it on the trailer while I am trying some of the fixes this winter.
